AbstractA 595-unit adaptive optical system is designed for the 4-meter diameter high resolution astronomical telescope. The deformable mirror adopts PZT actuators with 300mm diameter reflecting surface. A debugging system is established in laboratory and closed loop results are obtained. The scheme of the system, the design of the wavefront sensor, the wavefront processing system and the control software are described in this paper. Special influence matrix measuring methods are for the first time used on this debugging system and show better results than the classic actuator by actuator method. The system is successfully closed loop to correct the simulated static aberration. Using FWHM as the merit, the corrected PSF equals less than 1.1 times of that of the diffraction limit. A 913-unit adaptive optical system has been developed and will be closed loop in laboratory based on the experiments of this 595-unit system.; A 595-unit adaptive optical system is designed for the 4-meter diameter high resolution astronomical telescope.
